Hi Steven,

From the second equation you know that the value of y is minus one third of the value of x minus 4. Take this knowledge of y and substitute it into the first equation. That is

2 x + y = 1


2 x - 1/3 x - 4 = 1

Now you need to solve for x. I would first multiply both sides by 3 to eliminate the fraction.
